Adsorption is the tendency of accumulation of molecular species at the surface of solid or liquid. Depending upon the nature of bonds or forces of attraction between adsorbate and adsorbent. It is classofied between physisorption and chemisorption. Which of the following gas molecules have maximum value enthalpy of physisorption?A. `C_(2)H_(6)`B. `Ne`C. `H_(2)`D. `H_(2)O`

1.	Adsorption is the tendency of accumulation of molecular species at the surface of solid or liquid. Depending upon the nature of bonds or forces of attraction between adsorbate and adsorbent. It is classofied between physisorption and chemisorption. Which of the following gas molecules have maximum value enthalpy of physisorption?A. `C_(2)H_(6)`B. `Ne`C. `H_(2)`D. `H_(2)O`
Answer» Correct Answer - D Since `H_(2)O` can be liquified easily. Hence it will have maximum enthalpy of physisorption. Correct Answer - D Since `H_(2)O` can be liquified easily. Hence it will have maximum enthalpy of physisorption.
